NONE of these answers my question: how does two or three functions that depend on each other for a survival benefit evolve through small incremental changes that are selected for a survival benefit? Your Youtube videos and links to Wikipedia only DESCRIBES stages that an eye might have gone through--not HOW is it possible to get from one stage to another. Even you must see that these are not the same thing and do not answer my question. Come on, according to your own link it has happened some 50-100 independent times! It should be easy to explain the mechanism. I'll paste it one last time for your ease in your reply:
Even if we presuppose an already vastly complicated cell to kick off the evolution of the eye, an eye makes absolutely no sense on its own. You need a mechanism to process the information and be able to do something about it to relate it to a survival benefit--or no increase in functionality will evolve. But wait, you don't need a light processing center to make decision if you don't have any light sensitive information to process. What came first, the ability to move, the ability to sense light or the processing center to ascertain some survival benefit from light and effect movement? Seems like all three are needed for any survival benefit to occur. But wait, it's worse than that. For there to be an evolved increase in functionality in the eye (like to discern shapes), you would need a massively more complex processing unit for there to be any survival benefit---but what survival benefit led to the evolution of the processing unit without the complexity of the eye already present? How did that happen? For reference, this would be the "mechanism" sense of the definition of evolution which you said was fact.
We have already answered all of this in detail but somehow you refuse to see it, purely because the facts conflict with your pre-held position.
I gave you the benefit of the doubt but youre just being purposely obtuse now.
